regrid2 installation problem agai n

[Matt Georgescu]

Li, the syntax that you are using seems correct.

Are you trying to average "to" a 3.5 degree lat/lon box. I've never even 
thought about averaging to a coarser grid spacing although, i think box 
averaging should do the job and is recommended for such a thing.

try setting the domain bounds before displaying:
set x 1 145
set y 1 73
d regrid2(slp,2.5,2.5,ba)
